As negotiations between Democrats and Republicans to avert a govenent shutdown continue, the Senate will vote at 10 p.m. on the House-passed bill to extend funding for four weeks, and members of the House have been asked to be available.

Shortly after Senate leaders set up the late-night vote, the office of House Majority Whip Steve Scalise released a statement to members regarding further votes: “Please remain in town and flexible and we will relay any additional information as soon as it becomes available.... We aim to provide ample notice (approximately one hour) prior to any potential additional votes.”

The current funding measure expires after midnight Friday.

The vote on the House measure is by most accounts expected to fail given opposition from members of both parties. Democrats will meet as a caucus at 8:30 p.m. to discuss strategy.

Senate Minority Leader Charles E. Schumer met earlier in the day with President Donald Trump and called the discussion positive, but said that differences remained between the Republicans and Democrats.

Republican leaders maintain no solution to avert a shutdown has been reached.

“I think Sen. Schumer has gotten so far out on this thing he’s trying to figure out how to get back,” Senate Majority Whip John Cornyn said.

White House Legislative Affairs Director Marc Short spent Friday evening jumping betweens the Cornyn’s offices and Speaker Paul D. Ryan’s. He continued to press for the four-week continuing resolution the House advanced on Thursday.

Brushing off questions about a possible negotiated agreement or shorter stopgap, Short said, “I think there’s a bill that the House has passed, the president is ready to sign. The question remains whether Democrats want to shut down the government and deny military funding.”
